argi

Argument parsing for the future 🚀

Features

• Macro-based approach, providing an intuitive way to layout a cli
• Rich auto-help generation, styling based off of python's click library
• Zero dependencies
• Speedy compile times
• Low binary bloat

This library is intended to be a replacement for both heavier structopt/clap-based interfaces due to amount of features contained within, as well as slim ones based upon pico-args due to the small workflow and compilation footprint. As this crate isn't fully battle-tested yet, smaller programs are a prime contender for usage with this library.

Usage

Place the following into your Cargo.toml file:

toml [dependencies] argi = "0.1.0-beta.4"

Examples

This example simply prints the time-tested hello world message:

```rust use argi::cli;

fn main() { cli!( help: "Demo command-line utility", run: (|_, _| println!("Hello, world!")) ) .launch(); } ```

This example is a more complex command-line interface which pretends to launch a website via the use of arguments:

```rust use argi::{cli, data};

fn main() { cli!( help: "Demo application which launches something", run: (|ctx, _| { let addr = data!(ctx => --address).unwrap(); let port = data!(u16, ctx => --port).unwrap(); println!("Address found: {}\nPort found: {}", addr, port); }), --address -a [text]: { help: "Address to bind to", }, --port -p [port]: { help: "Port number from 0 to 65535", } ) .launch(); } ```
